Calculating odds and probabilities for slot88 online classic slot machine games with 3 reels with 10 symbols on each reel is simplicity itself. You simply multiply the chances of hitting the correct symbol on each real times the chances of hitting it on the other 2 reels. The formula looks like this in fact:

But progressive jackpots are sometimes tremendous. Sometimes you can even find progressive jackpots of $1 million or more. In order to accomplish this, slot machine manufacturers had to become programmers, because realistically, a mechanical slot machine was limited to 3 or 4 reels with 20 or so symbols on each reel. A mechanical slot machine's reels are actual strips of metal, and having more than 20 symbols on each of them made them too large to actually operate the machine.
But with a random number generator program, a casino can set up "virtual reels" with an unlimited number
